Church of St.Martin Worle – 2013 Bell Overhaul
Travel to the church with all necessary tools and equipment.
Dismantle the bells and lower to the ground with all their fittings. Transport the bells to
the bellfoundry in London and the fittings to our works.
Leaving the listed fourth bell untuned, have the remaining five bells carefully attended to
under the tuning machine to agree in pitch with the fourth bell. Transport the bells back
to our works.
Take detailed measurements from the inside and outside profiles of the six bells and from
those measurements calculate new leading dimensions such as to bring the hanging radii,
wheel diameters and clapper throws into perfect alignment-
Cast a resin pad true and level onto the crowns of the six bells to form flat surfaces to
which new headstocks may be accurately mounted.
Remove the bearing assemblies from the headstocks for further use and dispose of the
remaining ringing fittings. Dismantle the bearings and discard the existing grease seals.
Wash away all old lubricant in our degreasing tank. Carefully inspect all internal
components and advise the parish of any problems found, seeking permission to proceed
with any necessary replacements at additional cost. Make new felt seals and fit them to
the plummer blocks.
Make a new headstock for each of the bells, all fitted with steel gudgeons set in true
alignment and with staple adjusting screws for setting and maintaining even clappering.
Send the headstocks for hot-dip galvanizing. Fit the headstocks to the bells, stock down
and balance, turning the bells to present unworn surfaces to the blows of the clappers.
Drill through and fit galvanized steel supporting bolts together with insulation washers
for fitting between the crowns of the bells and the bolt heads.

malleable iron clapper fitted with a Tuftol bush resiliently mounted in neoprene rubber,
together with an independent crown staple fitted with a stainless steel hinge pin and with
an insulation pad for fitting between the staple and the crown of the bell.
AII galvanized steelwork to be etch-primed and the remainder primed as appropriate with
a heavy zinc-rich primer and all then painted with two coats of top quality machinery
All timber parts of the ringing fittings to be treated with a heavy application of exterior
grade Cuprinol wood preservative.
Transport all back to the church.
Hoist the bells into the tower and hang true and level in the bellframe. Assemble all the
